Just two dots and a line, made of grains of light. You write anything, pay 21 sats over Lightning, and nohaha reads your words out to everyone watching. No reply, just the face.
If you get a real laugh (a panel of AIs has to agree it's that funny), you get half the jar. No sign-up, just a passkey and any Lightning wallet.
Inspired by Robert Sahakyants's cartoon Who Will Tell a Fable? (1982). Curious what stackers come up with.
